Design of Fuzzy Logic controller for Solar PV fed BLDC Motor with Zeta Converter for Precision Controlled System

This paper proposes a system of BLDC motor drive fed through a solar pv. To provide the required power to the motor, a zeta converter is used to boost up the voltage. A Zeta converter is $\mathrm{a}4 ^{\mathbf{th}}$ order DC-DC converter that is built with two inductors and two capacitors and able to work in either step up mode or step-down mode. The proposed system adapts a fundamental functioning of three phase inverter which is switching and this will eliminate the power losses. Fuzzy logic rules are written to control the speed of the BLDC motor. The hall sensor and the reference speed to compared using controller and it is provided as a feedback for the three phase inverter. With increased system efficiency, the proposed drive is built to work in various speed ranges. The proposed system is simulated through Matlab simulating software followed by an experimental setup.
